It can select two bits of data from four sources using common select inputs. The outputs may be individually switched to a high impedance state with a HIGH on the respective Output Enable (OE) inputs, allowing the outputs to interface directly with bus oriented systems. Ordering Information Device also available Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
